Why choose this Lumishore thru-hull light

• Smallest hull cutout in the lineup: only 5/8” (16.5 mm) — minimal hull penetration with professional low-profile flush fit.

• No external driver: built-in internal multi-channel driver simplifies installation to a direct 2-wire connection from power to light.

Key specifications

Compatibility & control

The ORA THX204 is a single-color light controlled by a standard third-party on/off switch only. Smart controller integration (i-Connect, EOS-Link, Lumi-Link, NMEA 2000, MFD) is not available for this model — those features are exclusive to the SUPRA dual-color and EOS full-color series.

• Control method: on/off switch (third-party supplied) — simple 2-wire connection
• No external driver required: driver is built into the light body
• Hull isolation kit: available separately for metal, aluminum, or carbon fibre hulls

Confirm hull thickness, internal clearance, bonding, and cable run length before installation.

Frequently asked questions

Does the ORA THX204 work with a Garmin chartplotter?
No — the ORA THX204 single-color series uses a standard on/off switch only. MFD integration via i-Connect, EOS-Link, or NMEA 2000 is not supported on ORA single-color models. For MFD-controlled lighting, see the SUPRA THX404 or EOS series.

What is the hull cutout size for the THX204?
The THX204 requires only a 16.5 mm (5/8”) perpendicular hole — the smallest cutout of any Lumishore thru-hull model. The profile protrudes 18 mm (0.71”) above the hull surface.

What is the difference between the THX204 and TIX204?
Both are ORA single-color thru-hull lights with built-in drivers and 2-wire installation. The key difference: the TIX204 has an interchangeable LED module serviced from inside the hull without hauling out. The THX204 has a smaller 5/8” cutout and a wider 110° beam; the TIX204 has a larger 1-1/8” cutout and a focused 60° beam.

Is the THX204 rated for continuous submersion?
Yes — IP68 rated for continuous submersion. Marine bronze housing with Borosilicate toughened glass lens.

What is the maximum boat size for the THX204?
Lumishore rates the THX204 for vessels up to 24 m (80 ft). It is suitable for transom, side-hull, and bottom mounting.

Is this a Garmin product?
Yes. Garmin acquired Lumishore in October 2024. The ORA THX204 Blue carries Garmin MPN 010-04514-00 and is sold through Garmin-authorized dealers including MyGreenOutdoors. The hardware and design are unchanged.

What warranty does the THX204 carry?
A 3-year warranty covers defects in workmanship from the date of original purchase.
